﻿NE ARCTIC SPECIES OF GASTERUPTIIDAE — TOWNES 133 



Forewing about 6.0 mm. long; top of head with very fine close 

 punctures and strong transverse wrinkling; temple weakly convex; 

 head about 0.37 as wide at the occipital carina as at the eyes; occipital 

 carina not distinctly separated from the head which merges with it 

 gradually, weakly reflexed, about 0.3 as wide as the flagellum, basally 

 with strong striae which are longitudinal dorsally and oblique later- 

 ally; propleurum about 1.1 as long as the width of the mesoscutum, 

 transversely rugosopunctate ; lateral lobe of mesoscutum polished, 

 with fine close punctures that arc somewhat confluent with fine trans- 

 verse wrinkles, also with some sparser larger punctures; ovipositor 

 sheath about 2.3 as long as the forewing. 



Blackish. Apical part of clypeus, mandible, and most of fore and 

 middle legs beyond coxae ferruginous to dark brown; flagellum except 

 basally often stained with ferruginous; tegula ferruginous to brownish 

 ferruginous; fore and middle tibiae with a white external stripe from 

 base to apex or sometimes this stripe reduced to basal and apical white 

 marks; fore and middle tarsi partly white; hind tibia with a subbasal 

 white mark; hind basitarsus of female usually marked with white or 

 whitish; abdomen with a lateral spot at apex of first tergite, apical 

 0.3 ± of second and third tergites, apical 0.2 ± of fourth tergite, and 

 apical 0.12 ± of fifth tergite ferruginous. Often, however, the abdom- 

 inal ferruginous marks are more extensive and in females may occupy 

 all but the basal and apical portions. Apical 0.1 ± of ovipositor 

 sheath white.
